The JJ Electronic 12AU7 / ECC82 is a medium gain dual triode built with the quality and reliability that we’ve come to expect from a JJ tube. This 12AU7 offers smooth tones and clear definition which is why it’s no surprise that this tube is often found in hifi equipment as well as guitar amplifiers.
